Government default is an empty threat because the president would be impeached for not finding a way to pay U.S. debt, a Republican congressman said Monday.

Rep. Steve King (Iowa) expressed frustration at continued use of the threat of government default in a tweet on Monday:

STOP talking about default. The 1st dime of each $1 of revenue services debt. Obama would be impeached if he blocked debt payments. C C & B!

"C C & B" likely stands for "Cut, Cap and Balance," the plan to cut spending, place caps on annual spending and add a balanced-budget amendment to the Constitution, which have been the stated Republican goals in the debate over the deficit.
